The Barracuda NG Firewall uses generic, unbranded block pages by default. You can change the HTML source of these pages to adjust the content and style to fit your needs. Each page has a predefined list of placeholder objects that are replaced on-the-fly by the Barracuda NG Firewall when the block page is delivered to the client. Custom block pages can only be used for services using the Forwarding or Distributed Firewall services. The HTTP proxy does not support custom block pages.
Block Page | Service | Action Triggering the Block Page |

Access Block Page | Firewall Service | Matching Deny or Block access rule with the advanced setting Block Page for TCP 80 set to Access Block Page. |
Application Control Block Page | Firewall Service / Application Control 2.0 | Connection blocked due to the action set in the matching application rule. |
